[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0032] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0033] As shown in Figures 1 and 2, the modular refrigeration device of the present invention includes:

[0034] Refrigeration module 100: acts as a cold source, generating cooling capacity;

[0035] Mounting module 101: serves as the mounting carrier for the cooling module 100, enabling quick assembly and disassembly;

[0036] Heat exchange module: connected to the refrigeration module 100 for heat exchange;

[0037] And, the control module.

[0038] Determine the requirements based on the user's desired cooling capacity, heat exchange module, and installation space; then select the appropriate refrigeration module 100, heat exchange module, and control module from the "module library"; make physical connections using quick-connect plugs (for refrigerant lines, power cords, and signal lines); after the system is powered on, the control module will automatically identify all connected modules and load the preset optimal operating parameters.

[0039] This application eliminates the need for welding during installation, greatly simplifying the process. Users only need to set a simple target temperature to start operation. The system dynamically adjusts the compressor 102 frequency, fan speed, and electronic expansion valve 104 opening based on actual load changes at the terminal, always maintaining the highest energy efficiency.

[0040] The control module consists of a communication unit, a distribution unit, and a data processing unit. The communication unit is electrically connected to the refrigeration module 100 and the heat exchange module. The distribution unit is electrically connected to the refrigeration module 100 and the heat exchange module. The data processing unit is electrically connected to the refrigeration module 100 and the heat exchange module.

[0041] The data processing unit acquires the operating data of the refrigeration module 100 and the heat exchange module, processes the operating data, displays it on the display screen, and generates diagnostic information.

[0042] In one embodiment, the refrigeration module 100 includes a compressor 102, a condenser 103, and an expansion valve 104. The compressor 102 is connected to the expansion valve 104, and the expansion valve 104 is connected to the condenser 103. The compressor 102 compresses the refrigerant, causing the refrigerant to flow through the expansion valve 104 and the condenser 103. The refrigerant absorbs and releases heat during the flow process, and the refrigeration module 100 serves as the core of the cold source. A fan 105 or a water-cooled plate is connected to the condenser 103.

[0043] In practical use, the refrigeration module 100 is configured with three condensers 103 and a fan 105 at one end. The fan 105 simultaneously dissipates heat from the three condensers 103, resulting in high heat dissipation efficiency and low cost.

[0044] When there are multiple refrigeration modules 100, it is necessary to connect the refrigeration module 100 to the distribution unit. The distribution unit is preferably a proportional valve 106, which is used to distribute refrigerant to the refrigeration module 100.

[0045] It should be explained here that the data processing unit acquires temperature data, pressure data, and power consumption data. When the temperature data is greater than a preset threshold, the allocation unit allocates more refrigerant to the corresponding refrigeration module 100, so that the refrigerant circulates faster. Although the overall power consumption is increased, the temperature of the entire system can be reduced more quickly.

[0046] In one embodiment, the heat exchange module is used for air conditioning. The heat exchange module can be ceiling-mounted, wall-mounted, floor-standing, etc.; the heat exchange module can be a fan coil unit.

[0047] In another embodiment, the heat exchange module is used to directly cool heat-generating components such as servers, battery packs, and medical devices. The heat exchange module is a liquid-cooled plate, which can directly contact heat-generating components such as servers, battery packs, and medical devices. Moreover, the liquid cooling method has high cooling efficiency.

[0048] In another embodiment, the heat exchange module is a heat exchanger, which can be a plate heat exchanger for cryogenic freezing or a shell-and-tube heat exchanger for process cooling.

[0049] In this invention, a power distribution box is also provided for providing and distributing electrical energy. The refrigeration module 100, the heat exchange module, and the control module are all electrically connected to the power distribution box. The power distribution box is connected to the mains power to realize the provision and distribution of electrical energy.

[0050] In this invention, a liquid storage tank 107 is also provided. The liquid storage tank 107 is connected to the refrigeration module 100. The liquid storage tank 107 is used to store refrigerant. Of course, when refrigerant needs to be replenished, it can also be replenished through the liquid storage tank 107.

[0051] In this invention, the installation module 101 is a shelf, and the refrigeration module 100 is detachably installed on the shelf. The shelf consists of vertical support rods and horizontal support rods, which are fixedly connected. The refrigeration module 100 is installed on the horizontal support rods and locked in place by bolts or other fasteners, giving this invention high flexibility and scalability. When the cooling demand increases, it is only necessary to connect an additional refrigeration module 100 in parallel or replace it with a larger capacity refrigeration module 100. Different types of heat exchange modules can be easily replaced or added to adapt to new cooling objects, such as changing from cooling air to cooling liquid.

[0052] This application also features simplified installation and maintenance, significantly reducing on-site installation time and costs, avoiding complex pipe welding and vacuuming operations, and allowing for rapid isolation and replacement of faulty refrigeration modules 100, minimizing system downtime. Repairs only require targeting specific modules without shutting down the entire system.

[0053] In practical use, multiple cooling modules 100 can be configured to improve the safety redundancy of the system. For example, if it operates in N+1 redundancy mode, when one cooling module 100 fails, the other cooling modules 100 can automatically share the load to ensure the continuous operation of the system.

[0054] Modular design allows the system to always operate at near full capacity with high efficiency, avoiding energy waste caused by "over-engineering"; manufacturers and distributors only need to stock standard modules, rather than thousands of customized products; although the initial investment may be slightly higher, the overall cost of ownership is lower due to its advantages in installation, maintenance, expansion and energy efficiency.

[0055] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0056] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
